A CORPORATION or wIscoN- .eppiicatioa med Deember 1, 1927. lserial No. 237,030.

This invention relates to improvements in baille trays for refrigerated display counters.

lit isone of the objects of the present 1n. ventionv to provide bale trays for refrlger- 5 ated display counters which insure a con# tinuous7 uninterrupted circulation of' air .from Athe counter cooling coils downwardly and forwardly to the front of the counter wherebyan active circulation of air will'be provided over' 1 and then upwardly and rearwardly to the upper portionl of the coils, the return circulation being suiiic'iently high so as `to prevent the' air from absorbing' an excessive amount of moisture from products displayed von the trays within the counter. l

A further object of the invention 1 s to provide a baiiletrayof the class described which'is readily removable from a counter and so designed and shaped that it may only 'be replaced in its correct position, 1 nsur1ng AVan air space between its rear portlon and.

the coil. A p. l

. A further object of the invention is to pro- .vide a baie tray of4 the class described of such shape and dimensions as to be shallowest at' its inner end adjacent the coil, and increasing in depth toward its forward endportion, the upper rear portion of the bailie alsolbeing spaced from the top rear portion of thecounter, and said space being greaterl vthan the greatest depth of the tray portion,

the top of the baiiie and .downwardly through the coils. i 'A further object of the invention is'to provide a baiile tray of the class described havingv an upwardly'angled forward end portion to cause the returning air current to be deflected upward1y,to.clear theA tops vof the average produce'held on said tray. A rfurther object'pof the invention is to provide a baiiie tray for refrigerated counters which will insure an economical circulation of cold'air without a direct contact with the counter contacts, thus avoiding the picking up of moisture from the goods in the course ofthe direct air circulation. herobject `olf-the invention is to `provide a baiiie tray ofthe classdescribed formed of a good conducting material, so that produce thereon receives a high percentage of conducted cold from below] thev baiie Without air circulation from the same source. v

i extending having the very highest degree of sanitation and cleanliness and presenting an attractive,

Aneat appearance. V A `further object of the invention'is to bae tray for refrigerated dis-l provide ab p play counters .which is of very simple construction, adapted for the purposes described.

is strong and durable and is well With the above and other objects in view,

the invention consists of the improved baffle tray, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing, in which the same `reference characters indicate. the same parts in all ofthe. viewsz.I

Flg.' 1 is a cross-sectional view of a re` frigerated displ the improved baiiie trays;

Fig. 2 is a sectional view taken on line 2.-2 of Fig. 1; and

Fig. 3 is a Aperspective viewof a baille tray....'. f

`Referring now more particularly to vthe drawing, it will appear that the numeral 5 indicatesl a refrigerated dis lay counter which is formed with a sligh ly forwardly inclined insulated bottom 6,- an. angularly glazed front portion 7, slidable doors 8 forming a rear, and a top portion 9. There is also withinthe counter a longitudinally extending. partially enclosed com- .'partment 1Q'in which is positioned a coil -11 by which means the interior of the counter is cooled.

Within Athe counter .and resting on the` ay counter equipped with p bottom portion thereof are a plurality of bafe trays .12, one of which is shown in detail in Fig, 3'. Said baiile trays are arranged" side by side and transversely ofthe counter. A s shown clearly-in Fig. 3, each baiiie tray the slope of the b ottom 'ofrthecounter,

is formed lwitlba flat platform portion bentfupwardly at its inner` end portion at y while the upper edgesv of said rails are slightly less sloping, supporting the top or platform 13 in a slightly forwardly inclined positiol The rails 15 at their rear end portions-are narrowed and turned upwardly angularly', as at 15', against the rear portion 14. The forward end portions of the rails 15 are tapered or reduced, as at 16. The platform portion, just inwardly of the reduced rail portions 16, is formed with an upwardly and inwardly angled `flange 17,

` of a comparatively small height, which acts as a lforward baie. Each baffle tray is formed of a good conducting material, as iron, and has a porcelain finish to enhance its appearanceand to render it easy to clean and sanitary.

As shownl in Figs. 1 and 2, the baiiie trays are 'removably positioned adjacent each other within the counter, with the rear rail portions 15v against the coil and the forward tapered portions 16 against the front portion of the counter. This arrangement is such that the trays may only be placed in The portions 15 their correct positions. space the portions 14 from the coil assuring vertical air ducts adjacent the coils .which 'communicate with slightly forwardly in-l clined ducts between the counter bottom portion and the platform portions of the trays.

In use, produce is displayed on the platform portions of the trays, and the air circulation is as indicated by the arrows in Fig. 1, the air passing into the coil compartment between the tops of the trays and the counter portion 18, then downwardly,

being cpoled by the coils, and forwardly between the counter bottom and the tray platforms,'here cooling the material on the trays by conduction; The air leaves the forward end portions of the trays through the spaces between the tapered ends 16 and circulates What I claim as my invention is: -v 1.A bale ,tray for refrigerated Idispla counters, comprising a platform portion, a comparatively short front baille extending upwardly from the front edge of the platform portion, a rear batlie extending 'upwardly from the rear portion of the plat-v form portion and of a considerably greater height than the front baffle, and spacing rails projecting from said rear baffle andthe platform member and extending longitudinally of the latter."

2. A baffle tray for refrigerated display counters, comprising a platform portion, a comparatively short front baffle extending wardly from the rear portion of the plat.- form portion and of a considerably greater height than the front baile, and spacing rails projecting from' said rear batlie and the platform member, the platform portion at its front end terminating short of the lrails so as to provide a duct outlet'opening.`

3. A baiiie tray for refrigerated display upwardly from the front edge of the plat-fy form portion, a rear baflie yextending upf` counters, comprising a `platform portion, a

rear haiile portion extending upwardlyl therefrom, and rearwardly tapered 'rail members depending'from the platform, said rail members also being continued upwardly against said rear battle portion.

4. A baffle tray for refrigerated display counters, comprising a platform portion, ay

rear baille portion extending upwardly therefrom, and rearwardly reduced rail members depending from the platform and extending forwardly of the front edge of the platform, said rail members also being continued upwardly against said rear baile portion.

5. A baiile tray for refrigerated display counters, 'comprising a substantially horizontal platform portion, a' comparatively short front baffle extending upwardly from the front edge of the platform portion, a

rear portion of the platform portion and of a considerably greater height than the front baiile, and rearwardly reduced rail members depending from the platform portion and extending forwardly of the front edge of the same, said rail members also being continued upwardly against said rear baffle,

`the entire tray being formed 'of a porcelain coated, heat conducting material,

In testimony whereof, I aiix my signature.
